Lawyer. Demon. Lily Knight is both-half-human, half-succubus, and utterly dangerous.
Lily protects her secret and the safety of those around her by abstaining from the skin-to-skin contact that would grant her superhuman powers. An ambitious criminal prosecutor, she's all work and no play, determined to prove herself in the courtroom to atone for the ex-lovers she's left for dead in her past.
But after a fellow succubus turns up murdered and the police arrest an innocent man, Lily discovers evidence of a supernatural killer stalking the foggy San Francisco streets. And when human justice falls short, she launches an unsanctioned investigation to find the real culprit.
To stop the killer, she must embrace the full power of her heritage and risk the soul of the handsome suspect she can't help but fall for. Can Lily face her true nature without losing her humanity-or will she become the monster she fears most of all?
